Abstract

Abstract A foundry mixing machine is disclosed for mixing a mold material component with a binder component comprising a rotating rotor means to mix the components by action of centrifugal force. The invention is suitable for use with multi-component binders being able to mix two of the three components by a first mixing means and to mix the remaining component with the mixed components by a second mixing means. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation of the scope of the claimed subject matter.
